To all whom it may concern.-

Be it known that I, EDMOND REDMOND, of Rochester, in the county'ofMonroe and State of New York, have invented a new and useful Improvementin Apparatus for Trimming Ships, of which the following isa full and accurate description, which will enable others skilled in the art to whichitappertains to use the same.

My invention relates to means for making ships maintain an uprightposition in the water during a cross-wind, or at other times when avessel would ordinarily heel. Heretofore vessels were trimmed byshifting weights from the lee to wind ward side. This plan made itnecessary to carrya large extra weight of ballast, in order that itmight have the required effect when it was shifted from one side of theship to the other, and on yachts it was not available. My inventionconsists of an outrigger or counter-weight applied to the windward sideof the ship, the main weight of which counterpoise consists of watercarried in a tank at the outer extremity of the outrigger.

In the drawings, Figure 1 showsa deck view of a boat equipped with theapparatus. Fig. 2 is a vertical cross-section of aboat provided with theapparatus. Fig. 3 is a device by which the counterpoise can be drawn inor out laterally. Fig. at shows avertical section of the universal jointby which the fixed end of the outrigger-arm is attached to the boat,together with the tube by which water is conveyed to the tank. Fig. 5shows the outrigger extended over the side of the ship and held inposition by the ropes n n, which are attachable at their free ends tothe cleats s s, and form a simple way of adjusting and controlling thehorizontal movement of the tankarm.

Similar letters refer tosimilar parts through out the several views.

The tank 0, extended out from the side of the ship A by the arm B, towhich itis attached, will hold water, the weight of which, being on thewindward side, will counteract the tendency of the ship to heel toleeward. The water is conveyed to the tank through the pipe D from thepump E drawing from the body in which the ship is floating.

When the ship is changed in her course from one tack to another, and theoutrigger is to be changed from one side of the ship to the opposite,the water in the tank is firstlet out by raising the valve 0, by meansof the lever h, and working the rod 9, bell-crankf, and valve-rod d.When the water is discharged from the tank, the outrigger can be raisedby the rope 1' running over the pulley K on the mast G, and drawn in by.the con trivance shown in Fig. 3, in which the rope it, working on thepulleys m m, is attached to the outrigger-arm B, which it moves back orforth as the pulley m is revolved by the crank shown in Fig. l. I do notconfine myself to the use of the apparatus shown in Fig. 3 forcontrolling the motion of the arm B. Ropes attached to each side of thearm B, midway of its length and running to cleats on the gunwale ordeck, would serve to control the horizontal motion of the outrigger, anda block and tackle connecting G and D in the line i would answer to liftthe outrigger. A pump set in the tank and worked from the ship could beemployed to fill the tank, drawing water through a pipe let down fromthe bottom of the tank. The end of the outriggerarm on deck is providedwith a ball-andsocket joint a b, or its equivalent, which, being fixedto the ship, forms afulcrum for the lever-arm B. The weight of the tankwill rest on the gunwale of the ship oron the tackle 2',

or other suitable support, as may be desirable. The tube D, for carryingwater from the pump to the tank, can be flexible where it is used inconjunction with an independent arm B; or, for small boats, the tube mayserve as the arm to support the tank, in which case it would be of metaland have a suitable joint where attached to the pump to allow it therequisite motion.

When the apparatus is to be put in operation, the arm which carries thetank mustbe extended from the ship and secured. Water is then forcedinto the tank through the pipe extending thereto from the pump. As thewater rises in the tank its weight, acting on the lever formed by thearm, tends to depress the side of the vessel from which it is extended,and the ship is thereby brought nearer to the position in which it willsail fastest-- that is, on even keel.

On sailing yachts designed for speed the invention must be speciallydesirable, as it will hold the vessel upright in a beam-wind and enableher to sail closer to a head-wind. Where desirable the tank 0 can bemade of canvas or other flexible material, so as to be collapsible whenstowed away.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination in an outrigger for ships, of the arm 13, joint a 1)connecting said arm to the deck, tank 0, secured to the free end of saidarm, valve 0 in the bottom of said tank, and means for operating saidvalve, pump E, located on the ship, tube D connecting said pump andtank, and means for controlling the movement of the arm substantially asdescribed.

2. In the art of trimming a ship an outrigger consisting of an adjnstable arm that is extended from the side of the vessel and whichcarries at its extremity a tank that is held above the water in whichthe ship is floating, by said arm; the tank to be connected withapparatus by which water can be thrown into it or discharged therefrom.EDMOND REDMOND.
